A subset of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) data were used to produce a set of map images depicting the general geochemistry of the conterminous US. Approxiamately , samples from the continental US were analyzed. These consisted of solid samples, including stream, lake, pond, spring, and playa Cited by: 7.

Introduction. Between andthe U.S. Geological Survey (USGS) conducted a low-density (1 site per 1, square kilometers (km 2), 4, sites; see fig. 1) geochemical and mineralogical survey of soils in the conterminous United sampling protocol for the national-scale survey included, at each site, a sample from a depth of 0 to 5 centimeters (cm, termed the top 0- to 5-cm.

A multi-element soil geochemical survey was conducted over the conterminous United States from – in which 4, sites were sampled representing a density of 1 site per approximately 1, km 2.
